Fluent material dispensing system and a dispensing mechanism therefor

A dispensing mechanism for a bottle or cartridge configured to hold a fluent material, the dispensing mechanism comprising:

• a lever with actuation thereof causing a plunger to slidably engage an inner sidewall of the bottle and travel in a first direction towards an outlet of the bottle to expulse the fluent material therefrom;
• a portion stop at a defined location along the path of travel of the lever, with the distance traveled by the lever limited by contact of the lever with the portion stop located within the path of travel, thereby limiting the distance traveled by the plunger to limit an expelled amount of the fluent material to a corresponding defined portion;
• and
• a handle aligning with said first direction, the lever pivotally coupling to and being received at least in part within the handle, wherein the lever and the handle are shaped to facilitate cleaning thereof without requiring disassembling thereof.

A dispensing mechanism for a bottle or cartridge configured to hold a fluent material, the dispensing mechanism comprising:

• a lever operable between a rest position and an engaged position, which causes a plunger to slidably engage an inner sidewall of the bottle and travel in a first direction towards an outlet of the bottle to expulse the fluent material therefrom;
• a plate having a plate aperture, the plate movable between an upper position and a lower position;
• an elongate member passing through said plate aperture, the elongate member operatively coupled to the plunger and extending along the first direction, wherein pivoting motion of the lever from the rest position to the engaged position causes the plate to bind with the elongate member and move in the first direction from the upper position to the lower position, the plate and the elongate member thereby causing the plunger to travel in the first direction;
• and
• a cap for attachment to an end of the bottle opposite the outlet, the lever pivotally coupled to the cap, the cap enclosing an interior and wherein the plate is in fluid communication with said interior of the cap.
